RELASTlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 535,536, dated March12, 1895.

Application filed December 21.1894. Serial No. 532,520- (No model.)

To aZZ whom it may concern.-

Be it known that 1, ANDREW D. GARDNER, a citizen of the United States,and a resident of Lynn, in the county of Essex and Commonwealth ofMassachusetts, have, invented a new and useful Improvement inRelasting-Machines, of which the following, taken in connection with theaccompanying drawings, is a specification.

My invention relates to improvements in that class of relasting machinesin which the operation of relasting is performed by a shoe horninterposed between the shoe and the last and drawn by a treadle andconnected mechanism, and consists of the form and arrangement of themechanism connecting the treadle and horn as hereinafter morespecifically described and claimed.

The object of myinven tion is to so regulate the action of the hornwhile being drawn from between the shoe and last in the operation ofrelastin g that no undue strain will be brought on the upper which willtend to tear or otherwise injure the same.

The further object of my invention is to produce a simple and easilyoperated machine of the class above referred to.

My invention is illustrated by the accompanying drawings, in which-Figure 1 is a perspective view of a machine embodying the same, and Fig.2 a side view showing a modification thereof.

In the drawings A represents a standard suitable to support the workingparts of the machine, and from the top of which projects the usualspindle a by means of which the last is held in position.

D represents the horn guide and B the curved guide way along which theguide D is movable.

As shown in Fig. 1 of the drawings the guide way B consists of alongitudinally curved slot formed in a rigid arm b projecting from thestandard A, and the horn guide D of a suitable roll movable along theslot B, but it is evident that the guide way B may consist of alongitudinally curved rod, and the guide D of a suitable collar or otherdevice movable along the same, as shown in Fig. 2 or the constructionmay be otherwise modified without departing from the essential nature ofmy invention.

T represents the treadle and H the shoe horn. The treadle T is fulcrumedon the standard A and provided with a suitable counter weight W. Thehorn H may be of the usual form used with this class of machines.

The horn guide D is connected with the horn H and the treadle T bysuitable connections whereby a depression of the treadle T moves theguide D along the guide way B and draws the horn H from between the shoeand last.

With regard to the shape or curvature of the guide way B, it will besufficient to say that the guide way B is curved downwardly andlaterally (toward standard A) in such manner that as the guide D passesalong the same the horn H is gradually brought into a vertical positionand drawn out at the heel without any undue strain on the upper.

I will now describe the mechanisms connecting the horn guide D with thetreadle T and horn H, as shown in the drawings, but before doing so Iwish to state that I do not consider my invention limited thereto asmany equivalent devices will readily suggest themselves to one skilledin the art, the substitution of which would involve no departure from myinvention.

To a suitable bracket E on the standard A is pivoted the lower arm ofthe toggle P, the upper arm of which is forked and pivotally connectedwith the guide D on each side of the arm I). From the lower arm of thetoggle D projects a shoulder 19 to which is pivoted a connecting rod Vwhich is also pivoted to the treadle T, the above arrangement being suchthat by a depression of the treadle T the toggle P is bent and the guideD moved downward along the guide way B, and when the pressure on thetreadle is released the counter weight W acts to straighten the toggle Pand raise the guide D along the guide way B. A suitable stop e on thebracket E limits the upward motion of the treadle.

As shown in the drawings the horn H is mounted upon a horn carrier Lwhich is forked and pivoted on the guide D outside of the to gle P. Thehorn carrier L is provided with the longitudinal slots Z and Zalongwhich the ends of the guide D are free to move so that the horn H may bepushed back and advanced to adjust the same between the shoe and last,

a result which may be also accomplished by substituting for the carrierL a strap or other flexible device suitably connected with the guide D.

As shown in the drawings the carrier L is substantially rigid andrigidly connected with the horn H. The carrier L may be convenientlyprovided with a suitable counter weight n which raises the horn 1-1 outof the way of spindle a, when not in use, and causes it to drop downover the guide D in position to be advanced and adjusted between theshoe and the last.

The operation of my invention is described as follows :The fore part ofthe last being inserted in the shoe, the last is placed upon the spindlea, and the horn H is inserted between the last and the shoe, the pivotedslotted connections between the carrier L and guide D providing aconvenient means for securing this result. After the horn has beenplaced in the required position the treadle T is depressed bending thetoggle P and moving the horn guide D along its curved guide way B. Thecurvature of the guide way B determines the motion of the horn H and asthe guide D moves along the guide way B, the horn D is drawn over thelast and gradually inclined until it reaches the heel when it is drawnin a substantially vertical position along the counter of the last.

In forms of relasting machines as heretofore constructed the treadleconnections are so arranged that the power to draw the horn is appliedsubstantially transversely to the direction of its motion ale-n g thebottom of the last, and the horn is suddenly inclined and a great strainbrought on the upper, as the shoe is being drawn on to the last,particularly across the instep, and shoes are quite frequently torn orotherwise injured-thereby. By means of horn guide and its guide way ashereinbefore described, I produce agradual inclination of the horn asthe same is drawn, and secure an even pressureon the upper preventingany danger of injury thereto.

Owing to the arrangement of the toggle P and treadle connection, I alsosecure a machine that requires little power and can be operated with ashort stroke of the treadle.

I claim as novel and desire to secure by Letters Patent- 1. In arelasting machine the combination, with a suitable last support,a shoehorn and its operating treadle, of a horn guide, aourved guide way alongwhich the horn guide is movable and suitable connections between thehorn guide and the horn and the horn guide and the treadle,substantially as described.

2. In a relasting machine the combination, with a suitable last support,a shoe horn and its operating treadle, of a toggle lever one member ofwhich is pivoted to a fixed support and the other free to move along adownwardly and laterally curved guid e, said guide, and suitableconnections between the toggle lever and the horn and treadlesubstantially as described.

3. In a relastin-g machine the horn carrier L provided with thelongitudinal slots 1, Z, substantially as described and for the purposesspecified.

4:. In a relastiug machine the combination of a suitable standard A, aspindle a, supported thereby, a shoe horn H, a horn guide D suitablyconnectedwith the horn I-I, an arm I) supported by the standard A, thedownwardly and laterallycurved guide way B in said arm in which runs thehorn guide D, the toggle lever P one member of which is pivoted to abracket E supported by the standard A and the other member pivotallyconnected with the horn guide D, the shoulder 19 on said toggle, thetreadle T, and the pivoted connecting rod V connecting the treadle T andshoulder 19, all substantially as described and for the purposesspecified.

In witness whereof I have set my hand this 19th day of December, 1894,.

ANDREW D. GARDNER.
